• Manufacturer Part Number: HEDS-1300
• Description: Optical Reflective Sensors
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Absolute Maximum Ratings @ T
Notes:
1. Caution: The thermal constraints of the acrylic lens will not permit the use of conventional wave soldering procedures. The typical
2. Derate Maximum Average Current linearly from 65 C by 6 mA/ C [HEDS-1300 only].
3. Non-linear effects make operation of the HEDS-1200 below 10 mA not advisable.
4. 1 KHz pulse rate, 300 mS pulse width.
5. All voltages referenced to Pin 4.
System Electrical/Optical Characteristics @ T
Notes:
6. Measured from a reflector coated with 99% diffuse reflective white paint (Kodak 6080) positioned 4.27 mm (0.168 in.) from the
7. <Q> = Ipr/Ipt
8. Photocurrent variation with temperature follows a natural exponential law: Ip(T) = Ip(To)*exp[Ke(T-To)]
9. OSR size is defined as the distance for the 10%-90% “step” response of Ipr as the sensor moves over an abrupt black-white edge,
